PATCH 1/1 watchdog: alim1535_wdt: mark expected switch fall-through

In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through.

Notice that in this particular case I replaced "Fall" with a proper "fall through" comment, which is what GCC is expecting to find.
